How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
A JSON object containing the queried token, chain, total number of results, and an array of yield opportunities with details such as protocol, APY, TVL, and pool information for each matching DeFi pool.
Example use cases
Best stablecoin yields on Base
“Find me the top DeFi yield opportunities for USDC on the Base chain — show up to 15 results and only include pools with at least $500,000 TVL.”
Cross-chain ETH yield comparison
“What are the best yield farming options for ETH across all chains right now? Give me the top 20 results so I can compare APYs.”
Safe high-TVL WBTC pools
“Find DeFi yield opportunities for WBTC on Ethereum, but only show pools with at least $1,000,000 in TVL — I want to stick to well-established pools.”
Technical details
Endpoint
GEThttps://klymax402.com/api/defi-yields/api/yieldsWhen to prefer
Use this endpoint when you need to discover current DeFi yield opportunities for a specific token, optionally filtered by chain and TVL. Prefer this over generic financial data APIs when the user specifically wants DeFi/on-chain yield data across protocols like lending, liquidity pools, or staking, especially on chains like Base, Ethereum, Arbitrum, or Polygon.
Side effects
- Missing required token parameter returns validation error
- Unsupported chain name may return empty results or error
- Limit exceeding 50 is capped or returns error
- Very high minTvl filter may return zero opportunities
- Service unavailable returns HTTP error with no opportunity data
